POOR WATER QUALITY ADVISORY

A sample was taken from Clevedon Marine Lake on Monday 22nd July and the results indicate that the water quality in the lake is currently poor.

Test results are shared to allow lake users to make an informed decision about entering the water.  Anyone choosing to swim is advised to wear ear plugs and goggles to protect against infection.  All visitors having contact with the lake water are advised to wash or cleanse hands before eating.

The sample taken on 22nd July showed raised levels of enterococci, a naturally occurring bacteria normally present in sea bathing waters.  With lots of people enjoying the lake, sediment from the lakebed has been stirred up.  Combined with storm run-off and the hot weather, bacteria levels have risen.  Although UV in sunlight kills off harmful bacteria, it is only effective at surface level where the light can penetrate.

It is recommended that the public do not swim in the lake until the water has refreshed.  The lake will be drained on Wednesday 31st July so that it can refresh that evening at around 7pm with water from the Severn Estuary – and repeatedly during the next sequence of overtops between 31st July and 5th August.

The water quality will be retested on 7th August, after the overtops.

ADVICE AGAINST BATHING

Swimming in Clevedon Marine Lake is NOT ADVISED until further notice.

A sample was taken from Clevedon Marine Lake on Monday 22nd July and the results indicate that the water quality in the lake has decreased.

The lake will be drained on Wednesday 31st July so that it can refresh with water from the Severn Estuary, then repeatedly during the next sequence of overtops between 31st July and 5th August.

The penstocks will be opened around 8am on 31st July, and the lake should refill any time after 6pm.  Volunteers will be cleaning in and around the lake from 10.30am on 31st July.  Refills have become a popular spectacle to watch – as 30 million litres of sea water gushes over the seawall into the lake.

The water quality will be retested on 7th August, after the overtop.  Updates on the water quality in Clevedon Marine Lake are shared here.

There’s always lots to do at the lake in terms of litter picking, cleaning, muscle work and site management, so if you can spare any time to help out, please contact volunteer@marlens.org.uk

Slip hazard in small splash pool

Parents are encouraged to keep youngsters to the big splash pool (pictured) for the time being; it was cleaned and the water refreshed on Thursday, 18th July 2019, so is safe to use.  However, a slippery black algae deposit has been found in the smaller, upper splash pool and the channel between the two pools.  Volunteers will pressure wash and deep clean the small pool and channel next week – but in the meantime, there is a risk of slipping for any children standing on the black deposit.  Further updates on the algae clean-up will be shared here.

The splash pool area at Clevedon Marine Lake is very popular with young children, especially when the weather’s warm.  In February, over £4,000 was spent improving the drain works for the splash pools, to make sluicing and maintenance a lot easier for volunteers.
